Changes since v2: - Squashed "PM / OPP: Fix parsing of opp-microvolt and opp-microamp properties" into "PM / OPP: Parse 'opp--' bindings" Changes since v1: - Added missing SoB and upstream commit hash for "PM / OPP: Set cpu_dev->id in cpumask first" Original cover letter: This is part 1 of MOXA's PM / OPP / cpufreq backport series. The whole series aims to backport patches related to PM / OPPv2 and cpufreq which were included in the v4.4 kernel from TI's SDK. The end goal is to include cpufreq-ti and convert am33xx to using it and OPPv2. Part 1 here includes patches from the v4.5 cycle, listed in topological order: deaa51465105 PM / OPP: Add debugfs support 1c4d12de2719 PM / OPP: Add "opp-supported-hw" binding ffdb8cc7a27c PM / OPP: Add {opp-microvolt|opp-microamp}- binding af87a39a5f7c PM / OPP: Remove 'operating-points-names' binding 754dcf35f346 PM / OPP: Rename OPP nodes as opp@ dc4e7b1fa20a PM / OPP: Add missing doc comments 7de36b0aa51a PM / OPP: Parse 'opp-supported-hw' binding 01fb4d3c39d3 PM / OPP: Parse 'opp--' bindings fd8d8e63467c PM / OPP: Fix parsing of opp-microvolt and opp-microamp properties d9de19b1cc01 PM / OPP: Set cpu_dev->id in cpumask first 5ff24d601092 PM / OPP: Use snprintf() instead of sprintf() 3be3f8f36e73 devicetree: bindings: Add optional dynamic-power-coefficient property f8fa8ae06b8c cpufreq-dt: Supply power coefficient when registering cooling devices 929ca89c305a cpufreq-dt: fix handling regulator_get_voltage() result b331bc20d928 cpufreq: cpufreq-dt: avoid uninitialized variable warnings: Of these, dc4e7b1fa20a PM / OPP: Add missing doc comments was identified as a patch dependency, but otherwise serves no purpose. And d9de19b1cc01 PM / OPP: Set cpu_dev->id in cpumask first was found while looking through git logs. Last, 3be3f8f36e73 devicetree: bindings: Add optional dynamic-power-coefficient property is related to f8fa8ae06b8c cpufreq-dt: Supply power coefficient when registering cooling devices All other patches were included from TI's SDK. The patches apply cleanly on top of linux-4.4.y-cip. Please have a look.
